-★ Microwave scatterometer based on this idea. It is a figure showing an example. In the figure, 1 is a transmitter, 2 is a transmitter/receiver switch, 3 is a coupler, 4 is an antenna, 5 is a transmitted radio wave, 6 is the sea surface to be observed,
7 is a reflected echo, 8 is a receiver, 9 is a Doppler filter,
10 is a detector, 11 is observation data, 12 is an observation calibration changeover switch, 13 is an attenuator, and 14 is a calibration signal generator. Note that the same or equivalent parts in the figures are given the same reference numerals. It should be noted that the same or equivalent parts in the figures are indicated by the same reference numerals.

Claims

[Scope of utility model registration request]

A transmitter that generates transmission power, a transmitter/receiver switch that sends the transmission power generated by the transmitter to the antenna and the received signal received by the antenna to the receiver, and a transmitter that emits radio waves to the sea surface to be observed. A coupler installed between an antenna having a fibre-beam directivity that receives reflected echoes reflected by an object and the antenna of the transmitter/receiver switch, a receiver that amplifies the received signal, and a frequency analyzer that analyzes the received signal. It is equipped with a plurality of Doppler filters, a detector that detects the received signal selected by the Doppler filter, and a calibration signal generator that generates a calibration signal having a spread spectrum, and the calibration signal is transmitted to the coupler, the transmission/reception switch, and the calibration signal generator. A microwave scatterometer characterized in that a signal is applied to a Doppler filter and a detector via a receiver.
